Answer:
a. The number of people that receive the text in the fourth round are 10³ people
b. The total number of people that receive the text are 1.1111 × 10⁴ people
Step-by-step explanation:
a. The given information are;
The number of people the text is sent to in the first round = 1
In the second round, the number of people the text is sent to by people in the first round = 10
In the third round, the number people the text is sent to by the 10 people in the second round = 10 × 10 = 100 people = 10² people
In the fourth round, the number of people the text is sent to by the people in the third round = 100 × 10 = 1000 people = 10³ people
The number of people that receive the text in the fourth round = 10³ people
b. In the fifth round, the number of people, the people in the fourth round send the text to = 1000 × 10 = 10000 people = 10⁴ people
The total number of people that receive the text = 1 + 10 + 10² + 10³ + 10⁴ people = 11111 people = 1.1111 × 10⁴ people

a.
compare 1 side
CB looks about 4/3 as big as SR
so
ABC:TSR=4:3
b. reverse it
3:4
d.
if smaller is 3/4 of bigger then
a=1/2bh
if b and h are 3/4 smaller then
a=1/2(3/4)^2bh
a=1/2bh(9/16)
smaller is 9/16 compared to bigger so
16:9 is ratio
e. ratio is reversed
9:16
